Speciation events are important in the theory of punctuated equilibrium, which accounts for the pattern in the fossil record of short bursts of evolution interspersed with relatively long periods of stasis, where species remain relatively unchanged.

In the 1970s Stephen Jay Gould and Niles Eldredge proposed the theory of punctuated equilibrium which holds that stasis is the most prominent feature of the fossil record, and that most evolutionary changes occur rapidly over relatively short periods of time.

As the economist Joan Robinson pointed out in 1947, just about any exchange rate will be the equilibrium value for some combination of these other variables. The equilibrium exchange rate, she famously argued, is a chimera.
